Abstract
This paper proposes to optimize the control parameters of DC-link voltage shunt active power filter (SAPF) by Harmony Search Algorithm (HSA) and Total Harmonic Distortion (THD) reduction in the system. The aim is motivated by the need to minimize the burden on the DC-link capacitor voltage to enhance performance of a shunt active power filter. In particular the attention has been focused on the Hybrid Compensation (HC), including an active filter and Passive Filter (PF) distributed in Micro-Grid (MG) system. Each passive filter has been designed to eliminate main harmonics; connected to nonlinear load and Dispersed Generation Sources (DGSs) and gain reactive power while it is the duty of active filter with instantaneous power theory (pq), to correct unbalanced system as well as eliminate harmonic left. Simulation results are presented to validate the proposed scheme
